Well it seems to be solved. I just found out after not having received mms for a long time.
After last OS-update the mms settings was cleared. I typed in my providers settings and started to receive mms again. The battery does not drain anymore ?????
When these settings are missing, does the phone do a lot of communication on the network ???
After trying many different things, I was able to find a work around for this issue.
The issue that I had seemed to be from the Exchange accounts that I had associated with my phone. I turned push notification off and Fetch to manual. On the advanced menu, I did the same for all accounts, manual. This is keeping the phone frmo trying to check email until I want it to. If Mail is not active, it does not try to check email.
